Retagged music makes phone crash

So, I recently installed music brainz picard to fix my music library. It edited idv3 tags and structured my music in folders. I then added all that music to my phone. At first, over the USB cable, but then, by ejecting the SD card and adding it through a card reader.

The end result is that Xbox music crashes so much, it causes my phone to keep restarting every few minutes.

I factory reset, and left the SD card in with all the music. When I looked at the music app, the behavior started back up. Freezes, crashes.

I think it has something to do with music I got from Xbox music store being retagged that it REALLY doesn't like.
